Definitions

  • the invention relates to a cable distribution cabinet with at least one lockable door, which is pivotally mounted in the housing of the cabinet, and the cabinet is provided in the region of the connection of the housing and door with a rupture.
  • Cable distribution cabinets for use in the power supply especially cable distribution cabinets for low voltages, are well known in the art.
  • the distribution cabinets are usually installed outdoors and are preferably suitable for installation of distribution components for the public power supply and equipment components, such as traffic systems, pump controls, etc ..
  • Known cable distribution cabinets consist for example of plastic. Schrankober- / bottom part form a unit and are bolted or connected by a bolt-free locking slide with integrated break point.
  • the cabinet consists of individual parts, which are in particular assembled in a modular system.
  • the door lock is done for example by a three-point lock, suitable for the installation of commercially available semi-profile cylinder.
  • the short-circuit power in electrical networks and systems has increased sharply over the last few years. This also increases the power that z. B. is converted by heat in heat. This released heat energy as a result of short-circuit arcs can break cable distribution cabinets by pressure increase; the thermal expansion of the trapped air leads to an overpressure that can not be dissipated quickly enough by the existing vents. Furthermore, an additional pressure increase can take place by thermal decomposition of insulating materials, by increasing the volume or by forming explosive mixtures.
  • a cable distribution cabinet with the features of the type mentioned is from the DE 91 01 147 U1 known.
  • the storage of the door in the housing and the rupture protection is a functional unit.
  • the storage of the door in Holmenprofilen of the cabinet takes place directly on the rupture.
  • This is designed as a spring element, in particular spring steel sheet.
  • This design of the rupture protection an efficient pressure equalization is guaranteed in case of overpressure in the cabinet by a quick and all-sided lifting of the door from the side panels of the cabinet is possible.
  • a cable distribution cabinet with the features mentioned is further from the FR 1 405 441 A known.
  • a rigid locking bar between the rear wall of the cabinet and the door is locked with, so that in case of an explosion inside the cabinet, the door is secured against bursting.
  • Object of the present invention is to develop a cable distribution cabinet of the type mentioned so that it is burst-proof in a short circuit arc fault.
  • a deformation of the door between the pivot bearings in a short-circuit arc fault or even breaking a bearing point of the door in the presence of such a disturbance should be ensured that after reducing the pressure in the cabinet remains such a gap between the door and wall, which defines a defined Protection class for protection against contact.
  • a cable distribution cabinet of the type mentioned wherein the cabinet is provided in the region of the connection of the door and a wall of the housing with the rupture protection, which is designed as a band or rope connecting the wall to the door, said Berstelle adjacent the pivot axis of the door at this and the wall attacks and is disposed between the bearing points of the door.
  • the bursting protection is designed as a band. This can be due to its width very easy to assemble and allows different arrangements in the cabinet. It is particularly useful when the band is arranged in the manner of a loop, wherein the superimposed free ends of the band are connected to the wall or the door, in particular by means of a screw connection, and the loop end by means of a plug connection, in particular a producible and releasable without auxiliary tool connector, is stored in the door or the wall.
  • the formation of the band in the manner of a loop allows a relatively large power consumption of the band and also allows easy installation and easy replacement of the door.
  • the bursting protection in particular the band, is elastic.
  • the bursting protection of plastic, rubber or rubber with insert has such a length that after the bursting operation and reducing the overpressure in the cabinet, the door and wall are moved away from each other in the area of the rupture protection device by less than 50 mm, preferably less than 35 mm.
  • the advantage of the elastic design of the rupture protection is to be seen in particular in that energy is taken up by the rupture protection when applying the cable distribution cabinet with overpressure in the event of bursting, so that the wall and door side bearings of the rupture are claimed less. Furthermore, as a result of their elastic compliance, the rupture protection can stretch more, so that the high pressure in the interior of the cabinet can be reduced by a larger gap between the door and the wall. It can be accepted that this gap has a maximum opening of> 50 mm. Due to the elasticity of the bursting protection, the gap, as soon as the pressure inside the cable distribution cabinet decreases, degraded and then, with complete reduction of the pressure in the cabinet, the door and the wall moved a maximum of 50 mm away from each other.
  • the maximum gap can be, for example, by a shorter elastic band or rope maximum 12 mm, which corresponds to finger safety, so the stricter Protection class IP 2X according to EN 60529 is complied with.
  • This protection class is based on a tester with a diameter of 12 mm, in contrast to the protection class IP 1X with a test ball diameter of 50 mm, which corresponds to hand back safety.
  • the cabinet is particularly designed so that the door is mounted in opposite end portions, along a boundary edge of the door in the housing, be it in the roof, a lower segment or the wall of the housing.
  • the rupture protection is preferably in the range of the middle third between the bearing points of the door, in particular halfway between the bearings.
  • the door adjacent to the rupture protection, is provided with at least one molded part, which is parallel to the plane of the door effective and engages behind a molded part of the wall in the closed position of the door.
  • This arrangement has the task to prevent Wandalismus by a leverage of the cabinet is much more difficult in this area.
  • a resilient bursting these can when dismantling the high pressure in the interior of the cabinet, and thus the Zugurwölben wall and door, the wall and the door to move back to each other so that the moldings are transferred back into their rear grip position and thus the Normally open and close the door.
  • the Indian FIG. 1 illustrated cable distribution cabinet is illustrated without socket, which is buried in the ground. Also not shown are distributor components to be installed in the cabinet and device components.
  • the cabinet 1 has a housing 2 and a pivotally mounted in this door 3.
  • the housing 2 has a rear wall 4, a left side wall 5, a right side wall 6, a roof 7 and a front segment 8, which is arranged below the door 3 on.
